3 Ways to Build Strong Bones

It's easy to take our bones
for granted. After all, they do all their work behind the scenes. But when a bone
breaks, it's a big deal.
Bones take time to heal,
even for kids.

Having strong bones in childhood lays a foundation for bone health throughout life.
We build almost all our bone density when we're children and teens. The bone-building
process is mostly finished around age 20. As adults, we still replace old bone with
new bone, but more slowly. Over time, our bones get weaker.

Kids with strong bones have a better chance of avoiding bone weakness later in
life. As a parent, you can help by making sure kids get the three key ingredients
for healthy bones: calcium, vitamin D, and exercise.

1. Give Kids High-Calcium Foods

Calcium is a mineral
that's known for building healthy bones. It's found in dairy products, beans, some
nuts and seeds, and leafy green vegetables. It's also often added to foods like orange
juice or cereal.

What You Can Do

Encourage your kids to eat high-calcium foods:

If your child eats dairy, your doctor or dietitian can tell you how much to serve
based on age. Younger kids may need 2–3 servings of low-fat dairy each day,
while older kids may need 4 servings.

2. Give Kids a Vitamin D Supplement

Vitamin D (sometimes
labeled vitamin D3) helps the body absorb calcium. But most kids don't eat many foods
that contain vitamin D. Because vitamin D is so important, health care providers recommend
all kids take a vitamin D supplement if they don't get enough in their diet. Even
babies need to take vitamin D unless they're drinking at least 32 ounces of formula
per day.

What You Can Do

Ask your doctor, nurse practitioner, physician assistant, or a dietitian how much
vitamin D your child needs and the best way to get it.

3. Encourage Kids to Exercise

Our muscles get stronger the more we use them. The same is true for bones.

Weight-bearing activities like walking, running, jumping, and climbing are especially
good for building bone. They use the force of our muscles and gravity to put pressure
on our bones. The pressure makes the body build up stronger bone.

Activities like riding a bike and swimming don't create this weight-bearing pressure.
They are great for overall body health, but kids also need to do some kind of weight-bearing
exercise.

What You Can Do

Make sure your child gets at least an hour of physical activity each day, including
weight-bearing exercises.

Everyone needs to get enough calcium, vitamin D, and exercise. But these are really
important for kids — especially when they're growing during the preteen and
teen years. Vitamin D and calcium also can be useful as part of a medical treatment.
Health care providers often prescribe them when kids are recovering from fractures
or orthopedic surgeries, such as spinal
fusion for scoliosis.
